Superconducting Interface for a DC Circuit Breaker [PDF]

open access: yes8th IET International Conference on Power Electronics, Machines and Drives (PEMD 2016), 2016
High voltage direct current (HVDC) circuit breakers are a key technology to enable fault management for multi terminal DC (MTDC) networks. DC circuit breakers using superconductors for current limiting have been proposed previously and experimentally tested at low voltage levels.

Operating DC Circuit Breakers With MMC [PDF]

open access: yesIEEE Transactions on Power Delivery, 2018
High Voltage Direct Current (HVDC) grids may be protected from dc faults through the application of HVDC circuit breakers. Recent advances in dc circuit breaker technologies may allow faults in the dc grid to be cleared without a permanent loss of power to the connected ac grids.
